4.4. 6.4 Conformation. Introduction to Lactic Acid: Lactic acid was the first organic acid produced by fermentation process carried out in 1880. [6], Polymerization of a racemic mixture of L- and D-lactides usually leads to the synthesis of poly-DL-lactide (PDLLA), which is amorphous. Polylactic acid can be processed like most thermoplastics into fiber (for example, using conventional melt spinning processes) and film. By then looking at a VSEPR Table it is concluded that the shape is an AX4. 10. The name reflects the lact- combining form derived from the Latin word lac, which means milk. It has a role as a human metabolite. C3H6O3. lactic acid, its derivatives and polymer have been discussed. The various routes to polymerization and the companies presently involved in lactic acid production have been covered. Poly(lactic acid) is at present the most promising and commercially available bio-based and biocompostable (bio)plastic. PLA is produced from lactic acid, within a green production, which starts from sucrose obtained from sugarcane molasses as well as sugars derived from carbohydrate sources such as corn, wheat, potato, or cassava. This compound is more reactive than lactide, because its polymerization is driven by the loss of one equivalent of carbon dioxide per equivalent of lactic acid. The name "polylactic acid" does not comply with IUPAC standard nomenclature, and is potentially ambiguous or confusing, because PLA is not a polyacid (polyelectrolyte), but rather a polyester.[5]. The L- lactic acid rotates the plane polarized light in the clockwise direction whereas the D- lactic acid rotates the plane polarized light in the anticlockwise direction. Racemic and regular PLLA has a low glass transition temperature, which is undesirable. [32], PLA can degrade into innocuous lactic acid, so it is used as medical implants in the form of anchors, screws, plates, pins, rods, and as a mesh. It should serve as an excellent compilation for researchers and prospective researchers in this growing field of polymer chemistry. The structure, frequency distribution of molecules, dielectric properties, rotational correlation functions, and diffusion coefficients have been calculated. Uses. Biosynthesis 4. Microorganisms used in the lactic acid production are the species of Lactobacillus. The commercially produced lactic acid belongs to L (+) type. Thanks to its bio-compatibility and biodegradability, PLA has also found ample interest as a polymeric scaffold for drug delivery purposes. Though it contains hydroxyl functional group, it exhibits more acidic properties. It is a conjugate acid of a (S)-lactate. The fermentation broth is gently agitated to keep the uniform distribution of nutrients and air. Phosphate is transferred with NAD-dependent lactate dehydro­genase to pyruvate which reduces stereospecifically to L (+) or D (-) lactic acid (Fig. It is also used by food industry as preservative. Fermentation Process 5. Pyridine can also be used however this is less safe than ethylacetate and propylene carbonate. 6.2.2 Configuration 70. (Images to be added soon) The extended formula of lactic acid is CH 3 CH(OH)CO 2 … The recovery method varies depending upon the grade of lactic acid required. Get detailed, expert explanations on structure of lactic acid that can improve your comprehension and help with homework. Glucose, maltose, lactose etc. The PH of 1 mM of lactic acid is nearly 3.51. [12] The melting temperature of PLLA can be increased by 40–50 °C and its heat deflection temperature can be increased from approximately 60 °C to up to 190 °C by physically blending the polymer with PDLA (poly-D-lactide). (S)-lactic acid is an optically active form of lactic acid having (S)-configuration. Its widespread application has been hindered by numerous physical and processing shortcomings.
